Rotary vane pumps contain rotary vanes--broad blades--which are located in a cylindrical housing space. There is an inlet and an outlet. Air or liquid passes through the inlet where it is stored between each blade and exits through the outlet. Rotary vane compressors don't vibrate or shake like reciprocating compressors, so they operate at a much quieter volume.

This EM series in pumps are durable and compact. This one is ideal for extreme gaseous environments like pharmaceutical freeze-drying or refrigeration system evacuation. The EM series has become the industry standard for zero contamination of process and effective lubrication under high gas loads. 

The cooling fan prevents the motor from overheating by the use of a thermal overload device. This device has been designed to automatically reset and restart when the motor cools down, so no manual resets are required from the user.
